Cisco 2851 ISDN PRI D channel locked out - is this a config issue?

Switching from voice T1 with no D channel to ISDN PRI with D channel and the D channel is locked.  I have not been able to unlock it.  Verizon states they have provided me all the info I need to make this cut.  They also say that the circuit is good.  Assuming this is a configuration issue.    Using Cisco 2851 router.  What might be wrong?

Thanks.
